Still trying to figure out if my child has PANDAS --he did not have an acute onset of symptons----He has Autism and has had motor and auditory tics since he was 3 (when to me he'd fit that profile of PANDAS more) at that time he had a lot of OCD symptons--He is now 11 and has been experiencing almost daily and sometimes multiple times during the day headaches from mod to severe in nature for 6 months. He had some Bloodwork done in Dec 2009 which showed high TITERs and high Lymph--(did Keflex for 10 days ) repeated in Feb 2010 ---High titers , high Lymph, Low WBC----did 10 days of Zithromax-----repeated labs----Titers dropped to 417 (about 40 Points) Still waiting on DNASE--lymph still high at 50 and WBC came up but still low at 4.54-----Has anyone else's child bloodwork shown changes in their Lymph and WBC numbers?
